Idatha yezobuchwepheshe ye-Hydroxypropyl Methylcellulose
Nali ithebula elichaza idatha yobuchwepheshe evamile ye-hydroxypropyl methylcellulose (HPMC):
| Impahla | Inani |
|---|---|
| Isakhiwo samakhemikhali | Okuphuma ku-cellulose |
| Ifomula yamangqamuzana | (C6H7O2(OH)xm(OCH3)yn(OCH2CH3)z)n |
| Ububanzi besisindo samangqamuzana | 10,000 - 1,500,000 g/mol |
| Ukubukeka | Impushana emhlophe ukuya kokumhlophe |
| Ukuncibilika | Incibilika emanzini, ayincibiliki kuzincibilikisi zemvelo |
| Ibanga le-viscosity | 5 – 100,000 mPa·s (kuya ngebanga le-viscosity nokugxilisa ingqondo) |
| Ibanga lokushisa le-Gelation | 50 - 90 ° C (kuya ngebanga le-viscosity nokugxila) |
| Ububanzi be-pH | 4.0 - 8.0 (1% isisombululo) |
| Okuqukethwe umswakama | ≤ 5.0% |
| Okuqukethwe komlotha | ≤ 1.5% |
| Izinsimbi ezinzima | ≤ 20 ppm |
| Imikhawulo ye-Microbial | ≤ 1,000 cfu/g ngenani eliphelele le-aerobic microbial; ≤ 100 cfu/g yesamba semvubelo ehlanganisiwe nezisikhunta |
| Izincibilikisi ezisele | Ihambisana ne-USP 467 |
| Ukusabalalisa usayizi we-particle | U-90% wezinhlayiya ungaphakathi kuka-80 - 250 µm |
| Impilo yeshelufu | Iminyaka engu-2-3 lapho igcinwe endaweni epholile, eyomile |
Kubalulekile ukuqaphela ukuthi le datha yobuchwepheshe ingahluka kuye ngebanga elithile nomkhiqizi we-HPMC. Kuhlale kunconywa ukuthi ubheke imininingwane yomkhiqizo enikezwe umenzi womkhiqizo othile owusebenzisayo.
